OIL HEATING-STOVE.

SPECIFICATION forming pari; 0f Letters Patent N0. 500,7' 51, dated July4, 1893. Application filed March 17, 1893. Serial No. 466,445. (Nomodel.)

To a/ZZ whom it may concern.-

Be it known that I, CARL BRANDT, a citizen of the United States,residing at Cedar Falls, in the county of Black Hawk and State of Iowa,have invented a new and useful Oil Heating-Stove, of which thefollowing` is a specification.

This invention relates to heating oil stoves, and has for its object toprovide a device of this character that will feed the air through theburner and cause it to rise through a vertical tube in a heatedcondition and be fed downwardly through a spiral coil outside of thesaid vertical tube to the exterior of the stove at one side, and at thesame time cause an inflow of a current of air from the bottom of thestove upwardly through and around the said partsand outof the top tothereby quickly heat the air contained within a compartment and equalizethe temperature thereof.

With these and other objects in view, the invention consists of theconstruction and arrangement of the parts thereof as will hereinafter bemore fully described and claimed.

In the drawings: Figure 1 is a sectional per spective of an oil heatingstove embodying the invention. Fig. 2 is a transverse vertical sectionof the same.

Similar numerals of reference indicate corresponding parts in theseveral iigures of the drawings.

Referring to the drawings, the numeral l designates a cylindrical casinghaving supporting feet 2, attached to the same to suitably elevate thesame, and at the bottom of the inner side of said casing is located anannular flange 3, which supports vertical brackets 4, that embrace andhold an oil burner and reservoir 5, of suitable formation but preferablyof the construction known as j center draft, wherein the exterior air ispermitted to,r flow centrally up through and eX- ternally of a curvedwick located within a wick-tube that passes through the reservoir, andhas an oil-feeding connection with the bottom of the same. Thewick-elevating shaft 6 passes out through the casing 1, so that it maybe readily engaged to regulate the height of the wick 2X and control theiiarne. A horizontally-disposed plate 7, of circular form, is supportedfrom the reservoir of the burner on a level with the upper end of thewick tube and is formed with a circular groove 8 in the upper surfacethereof adjacent to the periphery of the same in which is secured thelower edge of a conical dome 9, having openings 10 therein covered withisinglass 11, or other suitable material, and at one side is formed withan opening 12 that is covered by a slide 13, wherebyaccess may be had tothe wick to ignite or extinguish the same, or for any purpose that maybe found desirable.

From the end of the wick tube a spreader 14 rises vertically and extendspartially up into the dome 9 to spread the iiame for evident andwell-known purposes. The upper edge of the dome 9 is formed with a seat15, at the inner termination of which is a vertical flange 16 thatremovably projects upwardly into a central tube 17, that has its upperend closed, as at 18, and the upper and lower ends of said tube areembraced by collars 19 having arms 2O extending therefrom, and rigidlysecured to a drum 21, of elongated cylindrical form, and wherein thesaid tube 17 is centrally located. The lower end of the drum 21 isilared, as at 22, and hinged at the back, as at 23, to the casing 1, sothat the said drum and tube 17 may be tilted backward to give access tothe burner, and in this movement the lower end of the tube 17 moves fromthe seat 15, the flange 16 being made of such length vertically as topermit the release of the said tube. On the upper end of the drum 21 isa cap 24, having a series of radial openings 25, which thereby make theupper part of the said drum open so that the air passing upwardlytherethrough may escape freely into a compartment in which the stove maybe placed.

Communicating with the upper part of the tube 17 is the upper end of aspiral coil 26, consisting of pipe of about the diameter of the tube 17and traveling downward around the said tube, but independent of thelatter except at the point where it connects therewith. The lower end ofsaid coil 26 passes out through an opening 27, in the drum 21, that islocated in a plane adjacent to the upper end of the dome 9, and theterminating end of the said pipe then extends upwardly in a verticalplane, as at 28, to permit the egress of the heated air into thecompartment. It will be seen that the coil 26, traveling through thedrum 2l in the manner set forth and as clearly shown, necessarily heatsthe interior of the said drum, and the air iiowing upward around theburner and its reservoir, through the bottom of the casing, and passingout of the top of the drum necessarily becomes heated by contactingwith, and flowing around, the said coil and also over the dome 9 whichbeinglocated close to the flame will necessarily impart a great amountof heat,which will be taken up and absorbed by the air. This double formof heating air is highly beneficial in that it requires only so much oilas is ordinarily employed in heating,Y a single column of air for thesame length of time and under the same circumstances, with theadditional advantage that owing to the rapidity of operation of thestove, as set forth, the temperature of a room both above and below willbe more quickly and uniformly equalized, and it will become necessary ina short space of time to regulate the burner in such lnanner as not togive forth so much heat, and therefore save the oil and decrease theexpense for fuel in heating purposes. It will be seen that the downwardtravel of the current of heated air directly from the burner through thecoil 26 is accelerated and assisted by the current of air coming throughthe bottom of the casing and passing up around the burner and around theparts of the coil because the temperature of the coil will thereby beproperly regulated continuously and uniformly to cause a proper flow ofthe heated current of air out through the lower end of the said coil.The lower part of the drum 2l is formed with an opening 29, suppliedwith a covering door 30, that is so positioned as to be in line with theopening l2 and slide 13 of the dome 9, and as previouslystated, the saidparts may be opened to gain access to the burner, especially forigniting purposes.

It will be understood that the drum, as Well as the casing, may besuitably embellished with designs, and supplied with openings withtransparent coverings at such points as may be found desirable and inthe same manner,

as is ordinarily done in stoves and heating devices of other forms andwell known to the art. It will also be seen that changes in the form,proportion, and the minor details of construction may be resorted towithout departing from the principle or sacrificing any of theadvantages of this invention.

A suitable liuc-pipe may be connected to the outer end 28 of the coilpipe, in order to have communication with a chimney or other escape toconduct unpleasant odors that may arise from the burning oil out of aroom and prevent the same from entering a compart-v the coil, as may befound desirable and necessary.

Having described the invention, what is claimed as new isl. In an oilheating stove, the combination of a burner, a dome mounted over saidburner, a tube with an upper closed end fitted on said dome, a drumsurrounding said tube and dome, and a coiled pipe havingits upper endcommunicating with the upper part of the said tube and coiled around thelatter downwardly, passing out of the side of the drum, to deliver theair-current from the burner into a compartment, substantially asdescribed.

2. In an oil heating stove, the combination of a burner with a domethereon that extends above the same, a casing surrounding said burner, adrum connected to said casing and open at the top, the lower end of saidcasing being open, a tube fitted to the upper end of said drum andclosed at its upper end to thereby inclose the flame of the burner, anda coil of pipe communicating at its upper end with the ripper part ofthe tube and extending around the latter downwardly and passing out theside of the said drum, substantially as described.

3. In an oil heating stove, the combination of a lower casing with anopen bottom, a burner and reservoir located in said casing, a drumhinged to the upper part of said casing at one side and formed with anopen top, and an opening at the lower part of one side thereof, a domemounted on said burner and inclosing the dame, said dome having anopening in one side covered by a slide and an upper seat with anupwardly-projecting flange at the inner part thereof, a tube centrallylocated in and rigidly held by the said drum and having its upper endclosed and its lower end open and resting on the said seat of the dome,and a spiral coil pipe having its upper end communicating and openinginto the upper part of the said tube and its lower end passing out theside of the drum, the said tube being located centrally of the said coiland surrounded by the latter, substantially as described.

In testimony that I claim the foregoing as my ownvI have hereto affixedmy signature in the presence of two witnesses.
